Honestly one of the best megaten games but not really one of my favourites.
The gameplay is kind of like the snes games but refined to a degree with certain elements changed like using magnetite to summon demons alongside keeping them active, however all of these changes were made for devil summoner on the sega saturn.
I don't really know what else to say aside from that you should probably check this out, not one of my personal favourites but good none the same
